Quintana uses a variation on a 3/4 motion to hide the baseball before he throws it.

The guy has a 88-91 fastball that's straight that he can place decently, a cutter that he doesn't spot that well, a curve that's probably his only average pitch, and a change that is below average. Eventually, the league will see him enough to get used to they way he's coming to the plate. And when that happens, it's going to be over for him.
